Measure daily temperatures over both land and water near a coastline, along with the wind speed and direction. The conditions can be recorded at a variety of altitudes. Using multiple earthquake recording stations, determine the epicenter of an earthquake by analyzing the arrival of the primary and secondary waves at each recording station. Real-time charts are generated, providing data that allows for the triangulation of the epicenter. Using an earthquake recording station, learn how to determine the distance between the station and an earthquake based on the time difference between the arrival of the primary and secondary waves. A real-time recording chart is generated, and the times between the waves can be measured. Drag two objects around and observe the gravitational force between them as the positions change. The mass of each object can be adjusted, and the gravitational force is displayed both vectorially and numerically as the distance between the objects is altered. ES 6.
